Greetings Holger!   
      
    HG>> Nowhere have I heard or read that a Yagi antenna has radials.   
    RW>> Well, you have heard it now.   
    HG> May you live long with your own theory.   
      
   I intend to.   
      
    HG>> The LPA antenna you are writing about has several driven elements   
    HG>> The lengts of the driven elements are staggered to achieve a broader   
    HG>> bandwidth.   
      
    HG>> I know this type particularly well because I have built and measured   
    HG>> several concepts for both 2 m and 70 cm and used them actively.   
      
    HG>> Behind the stack of driven elements there usually is a reflector and   
    HG>> in front of the driven elements directors.   
      
    RW>> That's the theory, anyway. And the one that Tom is advocating. IMO,   
    RW>> it is not a true LPA.   
      
    HG> That's not theory only, it is a working concept proven over the   
    HG> years.   
      
   In yadi'...yes   
      
    HG>> This antenna is often called a KLM-yagi because the KLM company was   
    HG>> the first to manufacture antennas of thes kind originally presented   
    HG>> in an article in QST.   
      
    RW>> I haven't ever read that magazine. It is too much ARRL oriented and   
    RW>> I'm not a fan of that organisation.   
      
    HG> They do however have a lot of different technical articles that I'm   
    HG> as a licensed technician am very interested in. As such I was also   
    HG> the first ham in OH that in 1956 built and used a SSB transmitter.   
      
   That's great, but old news.   
      
    HG> Well, that antenna concept was presented in the 1970's before you   
    HG> were licensed.   
      
   I was building antenna in the 60s. One does not have to be licensed to do   
   that.   
      
    HG> At that time I was building these antennas and used them to work   
    HG> Auroras as well as the first Oscar satellites and 2m contests.   
      
   Meanwhile, I was building antennas for a different service.   
      
    HG>> The other kind of LPA is one built on two booms insulated from each   
    HG>> other and fed from (often) the front end.   
      
    RW>> Correct and this is the subject of this LPA discussion.   
      
    HG> The discussion seems to have gone astray somewhere.   
      
   Yeah...   
      
      
       Have a day!
